CWE ID 79

Summary

CVE-2023-45683, also known as the SAML ACS Location URI vulnerability, affects the github.com/crewjam/saml library for the Go language. The vulnerability allows attackers to register malicious Service Providers at the IdP and inject JavaScript in the ACS endpoint definition, leading to Cross-Site Scripting (XSS) attacks in the IdP context during a SAML SSO Flow. This vulnerability poses a high risk to organizations as it allows attackers to perform authenticated actions on behalf of victims once their browsers load the SAML IdP initiated SSO link for the malicious service provider. The issue has been fixed in version 0.4.14 of the library, but users unable to upgrade can mitigate by performing external validation of URLs provided in SAML metadata or by restricting end-users from uploading arbitrary metadata.
